The difference between rotating wheels and forging wheels depends on three aspects: cost, appearance and performance. In terms of cost, the technology of pressing the wheels is relatively simple, suitable for mass production, low cost, while forging wheels are complex and cost-high, but the performance is good. These two shapes are difficult to distinguish, but they are very different in the characteristics of metal materials. The anti-fatigue, impact resistance, and pressure resistance of the forging wheels are stronger than the pressure of the wheel.   The wheels are stamped or forged.   It depends on what kind of spinning wheel hub. In terms of performance, it is definitely not as good as forging wheels, but if you use cold-rolled steel plates or forging wool, the performance is close to forging wheels. And this hub is less raw materials used in forging wheels, so it is more cost-effective in terms of cost and price.1. Don't blindly add the wheels. Some people increase the wheels to better improve vehicle performance. In the case of unchanging tire diameter, large wheels must be matched with wide flat tires to make the vertical swing of the vehicle smaller and improve the reliability. But the thinner the tire, the worse the shock absorption performance and comfort.   2. Do not have to choose your favorite wheels, but to obey the suggestions of professional and technical personnel, and choose a wheel that suits three distances.   3. Try to choose the wheels made of aluminum alloy profile. Compared with the previous cast iron wheels, the aluminum alloy-type wheels have greatly improved the ability to resist deformation, which is greatly reduced. The car driving force is small, run fast, save fuel, and heat dissipation. In addition, try to choose a simple wheel with a simple structure, because the complicated wheels of the structure are likely to be charged or refused to wash in a car wash shop.
